Radon is becoming a more widely documented gas. Property searches undertaken by the local authorities of behalf of property purchasers are becoming more intensive and aspects such as radon are now included as a standard search question.

Radon itself is a naturally occurring radioactive gas, which can enter buildings through the ground and is measured in units of 'Becquerels per cubic meter of air' (Bq m-3). Health studies have indicated a link between exposure to radon and an increased risk of lung cancer. The Health Protection Agency (HPA) has recommended that where radon levels within a property exceed 200 Bq m-3 the householders should take action to reduce radon to as low as is reasonably practicable.

The information provided by the HPA indicates that, according to the atlas of estimated radon levels, Adur District is within an area where between 1% and 3% of dwellings may be above the Action Level. This is the equivalent of 160 to 470 properties.

The actual level of radon within a dwelling can be measured for a small cost by the HPA, which involves detectors being placed within the property for at least three months.

  • Adur: The HPA advises that all of the dwellings actually tested for radon in the Adur District have been below the Action Level.
  • Worthing: We do not have any information for the Worthing Borough.
